xAI launches Grok 4.6, cheaper than rivals and built for long tasks
🧒 Discovery
Grok, Elon Musk's AI, just grew up: it can now read a text as long as a thick book in one go, and think harder or lighter depending on how tricky the question is.
📰 Essential
xAI unveiled Grok 4.6, featuring a 500,000-token context window and adjustable reasoning levels, available immediately through the xAI API and several partner platforms at roughly half the price of competing frontier models.
🔬 Expert
The 500,000-token window and four reasoning-effort levels target autonomous agents chaining long tool sequences without human input, a space where xAI is racing to catch up with OpenAI and Anthropic. The aggressive pricing, roughly half of rival frontier models, could squeeze industry margins if quality holds up over time.
